Prevalência e intensidade da infecção por parasitas intestinais em crianças na idade escolar na Cidade de Salvador (Bahia, Brasil)

Abstract

As part of a major study to evaluate the relationship between environmental changes and occurrence of the infection, prevalence and intensity of infection by intestinal parasites was studied in a sample of school children aged 7 to 14 years living in the City of Salvador. The prevalence of infection by at least one species of protozoa or helminth was 66.1%. Prevalence of infection by helminths increased with age. For all helminth species male children presented the highest prevalence.

Prevalência de enteroparasitas em município do interior paulista

“…Assim, as infecções por parasitos intestinais são de grande importância e relevância, não só pela morbidade resultante, mas também pela frequência com que produzem déficits, os quais podem comprometer o desenvolvimento físico e cognitivo das crianças [12][13][14] .…”

Sentinel areas: a monitoring strategy in public health

“…Comparison of these results with those to be obtained after the environmental intervention will indicate the impact of the sanitation construction work (Barreto et al, 1997;Strina et al, 1998). Studies are also being conducted on the preva-lence of intestinal parasites and reinfection rates in groups of schoolchildren (Prado et al, 2001); the environmental sanitation situation; seroprevalence and incidence of dengue virus infection ; risk factors for seronegativity for IgG antibodies against measles (Andrade et al, 1999); and perception of the environmental situation, from an anthropological approach (Killinger et al, 2000), among others. Based on the social and environmental characteristics of the "sentinel areas" and using multivariate classificatory techniques (principal components and cluster analysis), these 30 "sentinel areas" were grouped into four strata showing a strong correlation between environmental and social conditions and the level of health of their resident populations (Milroy et al, 2001).…”

Children's Environment in Brazil: From Domestic (Indoor) to Regional Threats

“…The studies suggest that geo-helminths represent a major public health problem and are an important indicator of the sanitary conditions in which a certain population lives. The association between the prevalence of intestinal parasitic diseases with socioeconomic and environmental factors was reported in the most of researches like: children from slums [71] or residing in townships with a low HDI in the N and NE regions, especially in rural areas [74]; households with no proper waste management and no solid residue collection [78]; the unhealthy condition to which this population is subjected [72,87], with a direct relationship with low maternal schooling [81,95] and low income family [80,[85][86][87][88][89][90][91]95]. The higher prevalence of Ascaris lumbricoides, Giardia duodenalis, Trichuris trichiura and hookworm infections in children living in contaminated environments [75,90,92,93] with inadequate daily caloric intake [94] may result in hospitalizations due to diarrheal disease [79], compromising their future anthropometric status [76,94].…”
